PILOT-BURNER.

Specification of Lett'ers 1aten1 Patented Dec. 21, 1915.

Application :nea March 1s, i912. serial No. 684,510.

Low, a citizen of the United States, residingat Chicago, in the county of Cook' and State of Illinois, have invented a certain new and useful Improvement in Pilot-Burners, of

which the following is a full, clear, concise,'

and exact description, reference'being had tothe accompanying drawings,` forming a fpart of this spec1fication. I

My invention relates to an improved 'construction of pilot burnersfor use in connec- .tionwith small steam boilersand particularlyboilers vfor 'use in connection with altomobiles.

By my inv'ntionI separate the main vaporizer from the pilot vaporizer so that ther two are -Sibected t0 v different heating conditions, the .pilotrvaporizer' being subjected to practically constant heatl whether the'main burner is operating or not, while the main vaporize'r is subjected to the heat from the pilot burner and also tof'a portion of the heat from the m'ain fire. The pilot vaporizer is alsol madeso thatnig-eis very readily removable to facilitate'repia'cingit with another' iffor any reason it gets out of order. k Y

By my invention I also' provide that the entire manipulation of the pilot. burner'rnay he controlled from a distant point, as 'for example, from the dash-board of. the vehicle -vfhen the device is used in connection with n automobile.

The several drawings illustrating my invention are as follows:

Figure 1 shows in top view the main removed. Fig. 3 shows in side elevation and partially in section the pilot burner and vaporizer. Fig. 4 shows in top view the arts shown in Fig. 3, the casing Ieing roken away to better illustrate thev relation of the parts. In this'fgure there is also shown. a portion ot' the main burner to -shOW its relation to the pilot burner. Fig. 5'. is a front elevation of the parts shown in Fig.v

3 to illustrateV the arrangement o 'f the inv terior of 'the pilot burner and itsoasing. Be it known that I, WILLIAM H.` WINs- Fig-6 shows in front elevation a portion of' the .mechanism'employed for-controlling the I controlling the eockassociatedm'ith the gas tank. f M Y Similar numerals irefertp' siiliilarA parts l throughout the several views..

The-header 6 is convnected directlyv with the pipe 4 and the.-

header 7 is formed in a loop of large diameter and connects with the supply pipe ex-v tending fromthe burner casing to a eol'itl'ol valve 9 from which the supply pipe extends to the main fuel tank, no t shown.

It wilI of course beunderstood that auto-A matic contre'lling devicesmay be employed.

in'the main fuel pipe 8 inv addition to the manually controlled valve 9. As such de- .,vices do not constitute apart of this inven- 'tiou, they'are not herein shown or described.

secured. In thisway thevalve 91may be controlled from any desiredr point distant l from thevaporizenaghfor example, from the dash-board 12 of mi automobile. Thel closed end of theheader 7 has secured to it by fusion, a clip 13 projecting over -a'nd resting upon the pipe 8 so that it may move freely thereon. The pipes 4 and '8, where .project through the casing 14 of theV the boiier, are secured to a plate 15 heldin place against the boiler casing by screws 16. The

plate 15 constitutes the only support for the v main vaporizer, as :if-result of which'the vaporizer is suspended underthe'boiler over the burner 1 so that the va rizing tubes 5 aredirectly over the pilot urner 17 whichv "i-'ziporif/.er rire free" toeonti for the lient elizinges Wli'ielitake place in itv f the s projects to' the left from the boiler easing as indient-ed.

The pilot-burner 17 consists of@ seperate "100 :burner strueture. secured to thefnmin ,burner "1- by meansfcf screws 47, as-indicated in'Fig.

4, said screws extending through a.' Hnge `.which serves to.,support the pilot burner from the main burner. The pilot burner 17 extends for some-distance outside-0f the oasing' 14 of the boiler and the projeeting portion .is surrounded by zin inclosing Wall 4B wit-hin which the pilot burner is divided into twoy portions 49 and 50 so that the'hezit produced Within the 48 `will be more evenly distributed around jthevaporizing tube 5l of the pilot'l burner The casing 4S is extended upward n suieient ldi'-t:1ne soY as to include :rsuielen't length of the' vapor-- yizer tube (i1-to properly vaporize. the -fuel suppliedto the. 'pilot ebnrm'sr and vthe tube al is providedgnear its upperend with two grooyes?A farting-aging the Sides of :1 slot formed' in the top of tile easing '18 to 'sup- N0 port the vripoii'zing tube'lanu the reguas shown at 57, and the only passages affording escape openings for the air and vaporized fuel from the mixing tube 56 into the burner 17 are thefsmall holes 58 formed in either side of the tube 56. This provides that if for any reason fuel supplied to the mixing tube 56 by the vaporiz'ing pipe 51 is not sufliciently vapor-ized, the liquid portion of the fuel is collected in'y the mixing tube, and runs out of the outeri end pf the tube, as a result of its inclination 1n the pilot burner, as indicated. y

The upper end of the vaporizing pipe al is provided with'a coupling member 69 which may be readily connected with or d1sconnected from the fuel supply pipe 18 by means of. a suitable union connector, so that in case of difficulty with the vaporizing plpe 51 or its controllin valve 54, the pipe and valve may be readi y removed and another inserted. The casing 48 is provided with a small tunnel-like openingO through its wall adjoining the boiler casing, and the pilot burnereopenings are continued through this opening although they are of restricted size at this point, as a result of which, 1f for any reason then pilot burner is blown out, the more protected portion of the burner ame contained within the casing 48 servesto againli ht the main portion of the pilot burner extending through the opening 60. Similarly, if for any reason the fire within the casing 48 is extinguished momentarily, the communicatiii jets through the opening 60 will again be hghted after the extinguishing cause has been removed.

To facilitate the ready inspection' of the' pilot vaporizer, the front wall 61 of the casing 48 is readily removable by undoing the screws -62, 62, and for thiscondition the vaporizer pipe 51 and its associated controlling tal'e 54 may readily be removed from the ,pilot burner-since the lower end of the vaporizer pipe is y contained in a slot 63 which is open at itsouter end. The'casing 48 is pref'ably secured tothe pilot burner frame by eans of the rew 64, 64, as indicated, and the inclined all over the sections 49 and 50 of the" -burner is provided with ribs or ns 65 Vto prevent undue heating of the casing.

In order to light the pilot burner, use may conveniently `be made of a burner tube. 66 opening through the lower portion of one of the sides of the casing 48, which burner tube is connected with the pipe 22 connecting with the acetylene generator. Spark termina ls 67 and 68 insulated from each other are mounted in lthe casing 48 in the path of the gas delivered from the burner tube 66, and these spark terminals areconnected with the` wires 25 and 26.

As a result of the construction shown and described, when` itfis desired to start the veither the handle 2l or the handle 21a,

y means of the jets4 pilot burner, either the switch 98 or the switch 33 is closed and the cock 23 is opened,

either by the rod 91 or the lever 80, as a produced between the spark terminals 67 and 68. Ventilating openings 69 and 70'are provided in the upper part of the walls of the vcasing 48 to facilitate the combustion of the acetylene gas in `the casing so thatit may properly heat the vaporizing tube 51. As the flame produced by the acetylene gas is very hot it takes 'but a moment to suiiciently heat the vaporizing pipe 51, for which condition the valve 19 is opened by means of "t being assumed that the controlling valve d'4 is left in proper adjustment to supply the right amount of fuel to the pilot burner` Owing to the particular construction of the main vaporizer, but a short time is required to sufiiciently heat it to vaporize the fuel required by the main burner, at which time the valve 9 is opened by means of either the handle 1l or the handleil, and the full fire is under the boiler. An opening 71 is made in the plate 61 of the casing 48, which normally is covered by a shutter 72 to facilitate lighting the ac etylene gas by a match if for ny reason 1t 1 s desired to do so, or if the lectrical ignitlon -system should temporai-ily fail-to operate. This special means for igniting the starting flame is ofv particular value in connection with adjusting the needle valve 54 so as to avoid the necessity for continuous operation of the sparking device and to ignite the gas at only the proper time during the adjustment.

As a result of the disposition of the controlling ring 92, the switch 98 and the valve handles 11a and 21a at the front end of the car, a convenient means is provided for controlling the entire operation of theJ pilot burner so that the needle `valve 54 may be properly adiusted for changing conditions, or, if desired, the needle valve 54 may be normally closed and the starting may be..

done entirely from the front end of the cai", depending upon the conditions under which the car is operated and the,l pleasure of the user. A. Whether the pilot burner is operated from the front end of the car or from the driver-s seat, it is to ,be borne in mind that the detent 82 retains the cock 23 in the position to which it may be actuated, owing to the mechanical connection between the two operating mechanismsl The double lever 77 is readily removable from the operating rod 75 of the cock 23 to permit removing the gas tank 24 from the car and substituting another tank` in its place, which is necessary in connection with the use of compressed gas, as is common in the art.

The eoelo; 9.7. lll; :nul HT provide r. convenlenty inerme for Sluiting' the pilot burner. either while the lampi# 93 und ill. rre ,in use or not. :15 ileeirerl.
